index and find

[Shi Mu]

what is the difference between index and find in the module of string?
for both "find" and "index", I got the position of the letter.

Re: index and find

>>> s = 'foobar'[color=blue][color=green][color=darkred]
>>> s.find('z')[/color][/color][/color]
-1[color=blue][color=green][color=darkred]
>>> s.index('z')[/color][/color][/color]

Traceback (most recent call last):
File "<pyshell#3 2>", line 1, in -toplevel-
s.index('z')
ValueError: substring not found


Pretty self explanatory.
